• manual broom

• crowbar

Classify the following lever

pincer

The force and resistance are equal in levers if ............................

• resistance arm > force arm

• resistance arm < force arm

• resistance arm = force arm

Second class lever, force = 200 Newton. Force arm = 5 cm,

calculate the resistance arm, When the resistance = 100 N.

• 10 cm

• 10 N

• 4000 cm

• 400 N

The type of levers which always saves effort

• 1^st class levers

• 2^nd class levers

• 3^rd class levers

The length of the force arm of a first class lever is 5 cm. and the

length of resistance arm is 15 cm. if the resistance has a value of 300

Newton, calculate the value of effort force.

• 100 N

• 300 Cm

• 600 cm

• 900 N

equal is the.....................
